It uses a 1\/8-27 thread size for mounting into the oil pressure port and a 10-32 stud terminal type for the gauge wire connection, matching the common terminal style used on many marine and automotive oil pressure gauge circuits. The sender's resistance output moves through a defined range as pressure rises: 120 Ohms at 0 PSI, 98 Ohms at 10 PSI, 77 Ohms at 20 PSI, 32 Ohms at 60 PSI, 25 Ohms at 70 PSI, and 17 Ohms at 80 PSI, giving a gauge calibrated to this range a consistent, repeatable reading across the full scale.\u003c\/p\u003e\u003cp\u003eThe housing is finished in white with a machined exterior, and the unit measures 3.63 x 2.75 x 2.5 inches and weighs 0.37 pounds. It ships as a single sender per package and is built to meet or exceed the performance of the original equipment part it replaces. Fit is universal, so it is not tied to a single engine make or model, making it a straightforward replacement wherever a Sender Code C, 80 PSI DS, 1\/8-27 thread, 10-32 stud oil pressure sender is required.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e OP24891\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSender Code:\u003c\/strong\u003e C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range:\u003c\/strong\u003e 80 PSI DS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e 10-32 stud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Range:\u003c\/strong\u003e 120 Ohms at 0 PSI, 98 Ohms at 10 PSI, 77 Ohms at 20 PSI, 32 Ohms at 60 PSI, 25 Ohms at 70 PSI, 17 Ohms at 80 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 3.63 x 2.75 x 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 023121248915\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 82514, 90511, A-2622, 02504-01, 872064, IA15003\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis oil pressure sender is a universal fit part, not tied to a specific make, model, or year range.
